In aircraft arresting gear of the type wherein a rope span is stretched transversely across the path of the landing aircraft, the retarding force exerted by the braking mechanism during arrestment is related directly to, and controlled directly by, the tension in that part of the rope adjacent one of the guide pulleys over which the rope is passed, and which pulley is arranged through suitable controlling means to control the retarding force in such manner that the force is, to a large degree, rendered independent of the inertia of the rope and braking mechanism. A rope a is led over pulleys b, b' and guide pulleys d, d<SP>1</SP> on either side of the runway and reeved over moving and fixed cross head pulleys e, e<SP>1</SP> of a hydraulic cylinder and ram arrangement f which, when compressed by de-' flection of the rope a discharges liquid into a pipe g<SP>1</SP> through which the flow is controlled by a needle valve g<SP>2</SP>. The rate of flow of liquid and consequent retardation of the aircraft is balanced by a piston m acting within a cylinder n and connected to the valve g<SP>2</SP> by an arm p and a rod l pivoted at k to a pair of links i, i<SP>1</SP> which in turn are pivoted on the structure at j and deflected by variations in the tension of the rope a. The pressure on the piston m is controlled through a pipe o from a cylinder v and a piston u acted on by a constant pressure piston q through the medium of a pivoted arm t and a sliding control s which may be manually controlled or automatically controlled by a rack and pinion mechanism (not shown) influenced by the movement of the ram f. In an alternative arrangement (not shown) the piston q may be centrally placed in a cylinder and controlled by differential pressures from a venturi placed in the pipe g<SP>1</SP>.

Abstract: 1,013,186. Measuring liquid level electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 15, 1963 [Feb. 15, 1962], No. 5817/62. Heading G1N. A liquid level detector includes a probe comprising a vibratory reed 1a, 1b connected into an oscillatory circuit and means for measuring changes in the amplitude of vibration. When the probe touches the liquid surface its vibrations are damped, and the change of amptitude may control a servomotor driving the probe so that it "hunts" about the surface. Alternatively the probe may be fixed to detect a predetermined level. Stainless steel arms are attached at their free ends to separate piezoelectric transducers 2, 3 vibrating the arms perpendicular to the plane of the V. In order to avoid errors due to the meniscus the V may be arranged in a plane at 45 degrees to the horizontal, and the amplitude of vibration made such that the tip of the V moves vertically through twice the height of the meniscus.

Abstract: 1,062,831. Electric measuring and indicating apparatus. AUSTIN CROMPTON PARKINSON ELECTRIC VEHICLES. March 30, 1966 [Feb. 11, 1965], No. 5888/65. Headings G1J, G1Q and G1U. For continuously monitoring the state of charge of a battery on load an ammeter 6 sensing the load current is combined with a volt meter 2 sensing the battery e. m. f. The ammeter drives a scale drum 4 and the voltmeter pointer 3 can be read against a fixed scale 5 calibrated in volts and also against the scale 7 on the drum 4, which is calibrated in fractions of charge life. The drum 4 also has a scale 4A calibrated to measure current, but in terms of hours of life which the measured current would allow. Thus in Fig. 1 the voltage is indicated as (approximately) 1. 8V, the discharge current as '3 hours' and the state of charge as (approximately) ¢ - i.e. sufficient to allow ¢ X 3 = 1¢ hours further running at the indicated current. It is possible to associate the scale 4 with the voltmeter and the pointer 3 with the ammeter; or to replace the pointer 3 by a second drum surrounding the drum 4, this second drum being transparent and carrying an oblique or spiral cursor line Figs. 3 and 4 (not shown). By extending the ammeter and voltmeter scales to the other side of zero, the same instrument may be used to monitor battery conditions during charging.

Filed: 1963-02-14
Abstract: 1,007,259. Lubricating. K. HIRATA. Feb. 14, 1963 [Feb. 14, 1962], No. 5957/63. Heading F2A. In a lubricant-applying device for wheels and/or rails, a lubricant supply-pipe 13, Fig. 2, has an eccentric 20 mounted thereon and fixed thereto by a pin 21, and a member 8 is mounted on ball bearings and surrounds the pipe 13. An annular cam 22 is mounted on the eccentric 20 and is attached to a member 14, which is mounted on the pipe 13 and is rotated by a handle 31 attached to the member 14 by screws 31a. The member 8 has a radial bore 24 therein which houses a piston 25, the latter being urged towards the cam 22 by a spring 26, Fig. 3. The radial bore 24 also houses a valve-member and a ball 27, the valve-member being urged by the spring 26 and the ball 27 being urged towards the member 30<SP>1</SP> by a spring 28. The member 8 has a lubricant-applying member 9 mounted thereon and a cover 17 is provided. The cover 17 is attached by bolts 18, Fig. 2, to a member 16, the bolts passing through the member 9. In use, in order to lubricate a rail C, for example, the device is positioned so that a periphery 9<SP>1</SP> of the member 9 engages the rail C and so that longitudinal movement of the device rotates the members 8 and 9 and thus causes the reciprocation of the piston 25 by engagement of the latter with the cam 22. Lubricant is supplied from a reservoir A, Fig. 1, and is passed through a filter 3, a valve 6, pipes 7, and 38 to the axial pipe 13, from where it passes between one end of the pipe 13, Fig. 2, and the cover 17, through the bearings 15, 15<SP>1</SP>, to a passage 29 in the member 16. The lubricant then passes from the passage 29 to a radial passage 30 in the member 8. On reciprocation of the piston 25, the lubricant passes from the radial passage 30, through a radial passage in the valve-member and into a longitudinal bore in the valvemember so that a reduced portion of the piston 25 is able to force the lubricant through the longitudinal bore, raise the ball 27 and allow the lubricant to enter a passage 10 in the member 9. The passage 10 leads to an annular recess in the member 9 which contains a felt 11 which conveys the lubricant to the rail C. Stroke adjustment of the piston 25 is effected by rotating the outer cam 22 about the eccentric 20. A graduated scale 13a is provided to facilitate stroke adjustment and seals 19 are provided. The device is urged towards one side of the rail C by a spring 36, Fig. 1, and is duplicated on the other side of the rail. In another embodiment, the top of the rail is lubricated and a single wider device is urged thereto by a pair of springs.

Abstract: 854,413. Photogrammetric plotting apparatus. NISTRI, U. Feb. 22, 1957 [Sept. 27, 1956], No. 6076/57. Class 97(1) A rod connected to the inner member of a gimbal mounting is movable in a fixed conical path and the rotations transmitted to the axes of the mounting govern the settings of two variable speed drives which move the drawing point along respective co-ordinate directions, the actual speeds being determined by the speed of a motor driving the variable speed drives, while their ratio, and hence the direction of movement of the point, is determined by the setting of the control rod. In the form shown a rod 9 terminates in a fork 10 carried on pivots 11 projecting from a hollow shaft 18 carried in bearings 19, 191. The fork carries a toothed sector 12 engaging a gear 13 on the same shaft 14 as a gear 15 which drives through a gear 16 a cylindrical rack 17 within the hollow shaft which also carries the bearings for the shaft 14. Thus any movement of the rod 9 in the plane of the drawing actuates the rack to rotate the gear 81 with which it meshes. Any movement of the rod perpendicular to the plane of the drawing rotates the shaft 20 and, through a helical gear, the gear 8. Variable speed drives 3, 31, both driven by a variable speed electric motor 1, drive flexible shafts 5, 51 at speeds determined by the settings of the gears 8, 8<1>. The ratio of these speeds is adjusted by rotation of a shaft 21 carrying a disc 22 having a notch 23 in which the rod 9 is held by a spring 24, the rotation being effected by a motor 28 in a direction and at a speed determined by the setting of a handwheel 29. The flexible shafts 5, 51, through leadscrews 6, 61, set the x and y co-ordinates of the plotting point 7, the resultant direction being determined by the setting of the handwheel 29, the speed being determined by the speed of the motor 1 as set by the resistance 25.
